Technology Used

Flow - Servomex's determination to deliver users the most safe, accurate and reliable levels of measurement remains at the forefront of our design philosophy. Therefore, our unique flow sensor technology has been placed before the measurement transducers, enabling positive flow conditions to be validated.

Oxygen – Servomex's unique zirconia cell which offers an accurate and stable measurement in a design that gives an exceptionally long service life.

Combustibles – Servomex's innovative Thick Film Calorimetry (Tfx) cell allows a user to make a sensitive combustibles analysis rather than a breakthrough indication. This gives even more precise control of the process which results in greater fuel savings and lower emissions.
